Observability - CI/CD Glossary Definition

Observability is the ability to understand a system's internal state from the logs, metrics, and traces it emits, so you can debug problems you did not anticipate.

Observability is the property of a system whose internal state you can infer from its external outputs: logs, metrics, and traces. In CI/CD it means being able to answer why a pipeline slowed down or a job failed without adding new instrumentation.

The three signals

Observability is commonly grounded in three telemetry types: logs (discrete events), metrics (aggregated numbers over time), and traces (the path of one request across services). CI pipelines emit all three.
